Benefits of technology

[0003]Uncontrolled peer-to-peer (“P2P”) distribution of content is widespread today and results in a significant loss of revenue to content owners. Controlled peer-to-peer sharing using digital rights management (“DRM”) technology would enable content owners to protect their rights while potentially providing users with the freedom to share and distribute content. Content owners would benefit from viral distribution of their content via increased sales.

Problems solved by technology

Uncontrolled peer-to-peer (“P2P”) distribution of content is widespread today and results in a significant loss of revenue to content owners.

[0078]Computing Sharing License

[0079]In one embodiment, as part of the information exchange phase, the receiving peer would send its personality node to the sharing peer and also a parameter that indicates whether the content key should be encrypted using public key encryption or secret key encryption. Depending on the value of the parameter, the sharing peer will use the secret key / public key mechanism for encryption.

[0080]If symmetric key binding is used, the Sharing Peer sends a command to the Receiving Peer over a secure channel asking it to encrypt the content key. The Receiving Peer will re...

Abstract

Systems and methods are described for peer-to-peer sharing of electronic content. In one embodiment, if a license associated with a content item permits a sharing peer to share the content item with a receiving peer, the sharing peer rebinds a cryptographic key associated with the content item to the receiving peer and generates a sharing license for the content item. The sharing peer sends the sharing license and the content item to the receiving peer for consumption.
